HYDRANT-OUTLET.

To all whom t may concern:

i Be it known that we, MURRAY O. LIN- sco'r'r and lVILLIAM A.MCINTosi-r, citizens of the United States, residing at Beverly, in thecounty of Essex and State of Massachusetts, have invented certain newand useful Improvements in Hydrant-Outlets, of which the following is aspecification.

This invention relates to hydrant outlets, and has for its object theprovision of a comparatively simple and thoroughly etiicient device ofthis character by means of which additional lines of hose may be readilyconnected to the discharge nipples of a hydrant or fire-plug withoutcutting off the water supply or in any manner interfering with the flowof water through the lines of hose already connected to said fire-plugor hydrant.

A further object of the invention is to provide a hydrant outletincluding a casing having its inner end communicating with the interiorof the stand pipe and its outer end threaded for connection with a hose,there being a spring actuated valve arranged within the casing andmovable to open position by an impact rod on the coupling member of ahose, when the latter is connected with the threaded end of said casing.

A still further object of the invention is generally to improve thisclass of devices, so as toincrease their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding' of the invention and the merits thereof,reference is to be had to the following description and accompanyingdrawing, in which:

Figure 1 is a Vertical section, partly in elevation, of a hydrant outletconstructed in accordance with our invention, showing the valve closedand a hose in position to engage the threaded end of the casing, thebody of the hydrant or fire-plug and cover being indicated in dottedlines; and Fig. 2 is a longitudinal sectional view showing the hoseconnected with the threaded end of the casing and the valve in openposition to permit the flow of water from the standpipe to said hose.

Specification of Letters Patent.

Application led February 28, 1911.

Patented Mar. 19, 1912i Serial No. 611,465.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The improved coupling forming the subject matter of the presentinvention is shown, by way of illustration, in connection with afire-plug of the ordinary construction, in which 5 designates the standpipe, 6 the casing, and 7 the lid or cover forming a closure for theupper end of said casing. The stand pipe 5 is provided with a pluralityof outlets 8 in which are seated valve casings 9 for connection with afire engine hose, and as these valve casings are similar inconstruction, a detailed description of one will suiiic'e for all.

The valve casing 9 is preferably cylindrical in shape and provided withexterior threads 10 for engagement with corresponding threads formed inthe walls of the outlet openings 8. The inner end of the casing 9extends within the standpipe 5 and is provided with a plurality ofdischarge ports 11 through which the water from the standpipe `Hows tothe hose, indicated at 12. Formed on the interior wall of the valvecasing 9 is a circumferential shoulder' 13 constituting a seat for alongitudinally movable valve 14'. The valve 14 is provided with a stem15 which latter projects through an opening formed in a transverse brace1G, with its outer end disposed entirely within the lines of the casing9, so as not to offer any obstruction at the mouth of said casing.

Secured to or formed integral with the rear face of the valve 111 is apin 17 which projects through the rear wall 1S of the valve casing andserves to center the valve as the latter is moved to open and closedpositions. interposed between the valve 14 and the rear wall 18 of thecasing is a coil spring 19 which normally and yieldably holds the valvein closed position. The outer' end of the casing 9 is exteriorlythreaded at 2O and is pro-vided with an annular shoulder 21, by means ofwhich the casing may be conveniently gripped with a wrench or othersuitable tool so as to facilitate threading the casing on the standpipe.

The hose 12 is provided with a clamping collar 22 having its outer endformed with a circumferential groove 23 adapted to receive the flangedend 24 of a union nut or coupling 25, the latter being provided withinterior threads for engagement with the exterior threads of the casing9, as shown.

Extending transversely across the clamping collar 22 is a bar 26 havingan impact rod 27 extending longitudinally from the center thereof andadapted to engage the valve stem, and open the valve so as to permit theflow of water from the standpipe through the hose when the latter isconnected with the casing 9. Thus it will be seen that when the unionnut or collar 25 of one line of hose is threaded on the outer end of thecasing 9, the free end of the impact rod 27 will bear against theadjacent end of the valve stem 15 and force the valve 14 rearwardlyagainst the tension of t-he spring 19, thus permitting the water in thestandpipe to flow through the ports 11 to the hose without cutting offIthe water supply, or in any manner interfering with the flow of water tothe lines of hose already connected with said standpipe.

Attention is called to the fact that the outer ends of the casings 9 areentirely housed within the cover 7 when the latter is in closedposition, so as not to offer any surface projection on the exterior ofthe fire-plug. v While the device is principally designed for connectingfire engine hose to hydrants, fire-plugs, and the like, it will ofcourse be understood that the same may be used wit-h equally goodresults for connecting adjacent sections of hose, or wherever a deviceof this character is found desirable or necessary. t will also be notedthat the threads 20 are coarse and the threads 10 relatively thin, whileone end of the coil spring 19 is seated in an opening in the rear wall18 of the valve casing, so as to center the spring with respect to thepin 17.

Having thus described the invention, what is claimed as new is:

1. The combination with a valve casing having its rear end providedwit-h outlet ports, a transverse bar arranged within the casing andprovided with an opening, there being an opening formed in the rear endof the casing and arranged in alinement with the first mentionedopening, a valve having a stem on one end thereof slidably mounted inthe opening in the transverse bar and provided at its other end with arod extending into the opening in the rear end of the casing, a springdisposed between the rear end of the casing and the valve for normallyholding the latter in closed position, and a hose coupling having animpact rod secured thereto and adapted to engage the adjacent end of thevalve stem for opening the valve when .the coupling is connected withsaid casing.

2. The combination with a fire-plug including a casing having a cover,of a standpipe arranged within the casing, a valve casing threaded in anopening in the standpipe and having its inner end provided with outletports and its outer end eXteriorly threaded, a transverse bar disposedwithin the casing near the outer end thereof and provided with anopening, there being an opening. formed in the rear wall of the valvecasing, a valve arranged within the casing and having one end thereofprovided with a stem extending through the opening in the bar and itsother end provided with a rod seated in the opening in the rear end ofthe casing, there being an annular shoulder formed within the casing andconstituting a valve seat, and a spring interposed between the rear endof the casing and valve for normally holding the latter in closedposition, the outer end of the valve casing being housed within thecover when said cover is closed.

In testimony whereof, we atIiX our signatures in presence of twowitnesses.
